Webmin is installed on the server that hosts this site and for the longest time I’ve been accessing it remotely through its default port at https://tech-otaku.com:10000. Despite connections being encrypted through SSL and having two-factor authentication enabled in Webmin this still presents a security risk.
Your Mac’s network name forms part of its network address. If you want to share your Mac’s files and folders with other computers on your network you’ll need to know its network address so that those other computers can connect to it. This information is readily available in System Preferences, but this article looks at how to get your Mac’s network name using the command line.
In general, the computers and devices that make-up networks are each assigned an IP address. The IPv4 address 192.168.75.0 is written in dot-decimal notation, a series of 4 decimal integers each separated by a period for clarity. For computers, this human-readable format is stored in binary with each decimal integer represented by 8 bits or 1 byte commonly referred to as an octet. The 4 decimal integers of an IPv4 address are therefore represented by 4 octets totalling 32 bits.
The ability to remotely access a computer on a home network while away from home can often prove very useful.
Employing a technique known as SSH (Secure Shell) tunnelling this article describes how to securely access files on a remote computer using AFP (Apple Filing Protocol) and share that computer’s screen using VNC (Virtual Network Computing).
There are occasions when we want to make a computer on a home network or LAN accessible externally on the Internet. For example, remotely connecting to a LAN computer using SSH or remotely accessing a web site residing on a LAN computer.
Each computer connected to a local network is assigned a dynamic IP address. On occasion it’s useful, if not essential, to assign a static IP address instead. As an example, port forwarding requires the destination computer on a local network to have a static IP address.
Using Mac OS X Lion 10.7.1, I’ll describe two ways of assigning a static IP address to a computer on a local network.
